Hi and what do i need to know

Hey guys, my first post =)
my names Alex from cannock in the uk and at the moment i'm not driving an E36 but give it 6 months and hopefully that will will change lol.
now i've looked at some buyers guides and looked at what i need to look out for, but is there anything i really need to look out for that may not be too well known?
also, what are the real world running costs like as i'm only a 21 year old student (i'm looking at a 318 btw)
and finally, whats the best too own and drive, i'm looking at a coupe or a compact, everyone seems to be slagging off the compact, but i relly like them and wondered if they really deserve there rep.
cheers for reading, Alex.
